DPF20 Frequency, rate, total or period counter
Instruction Manual
1. Panel meter DPF20
Counter, ratemeter and periodmeter, 96 x 48 mm (1/8 DIN)
Panel meter 96 x 48 mm (1/8 DIN) and 6 digits with 14 mm digit height,
configurable with 5 impulse counter modes
(see section 1.2)
, 2 rate
-
meter modes
(see section 1.3)
and a 1 periodmeter mode
(see section
1.4)
.
Highly configurable, accepts all types of sensors (NPN, PNP, push-
pull, Namur, inductive, pick-up, mechanical, TTL, CMOS, ...) including
quadrature signals (single and bidirectional encoder signals).
Reading from 999999 to -199999 with decimal point, scalable read
-
ing with configurable multiplier factor (1 to 999999) and configurable
divider factor (1 to 999999). Includes internal pull-up and pull-down
resistors, configurable trigger levels, detection by rising or falling edge,
excitation voltage configurable from 5 Vdc to 18 Vdc.
Options for output and control with 1, 2 and 3 relays, transistor out
-
puts, SSR drive controls, isolated analog outputs, communications in
Modbus RTU, RS-485 ASCII and RS-232. Special options with 4 and 6
relay outputs.
Independent alarms configurable as maximum or minimum, with 1 or
2 setpoints per alarm, hysteresis, independent activation and deacti
-
vation delays and control for inverted relay.
Front protection IP65. Connections by plug-in screw terminals. For in
-
dustrial applications.
• ‘
Fast access’ menu to selected functions, accessible with key UP (
5
)
(see section 1.19.12)
• Function ‘On power up’ for system protection on first ‘cold’ start-up
or automatic reset
(see section 1.19.15)
• Special ‘FAST’ mode for fast counting applications
(see section 1.16)
• Special ‘SLOW’ mode for slow ratemeter applications (low frequency
applications)
(see section 1.15)
• Direct configuration for most usual sensor, at the ‘
SnSr / Auto
’ menu
(see section 1.19.10)
• Function ‘Trigger Sense’ helps to detect the correct trigger level
(see
section 1.13)
